Why not just use a cardboard mailing tube.  If you need tape, try Post-it tape or Kapton tape.  Kapton is expensive, about $18/roll, but is easily removed even after seeing high temperatures of 200 deg Centegrade.  Kapton tape uses a silicon based adhesive.

You could also try for a flat send is to use either Kapton tape on the corners or a triange of paper and Kapton tape to hold the sheet flat on a backer board.  Then sandwich with another cardboard.

If you live in the states, I could mail the OP a sample piece of the tape.  Contact me via email.
